Walk about 2 kilometres a day. That's all it took in one large U.S. study to slash the risk of dying from diabetes by more than a third. Believe it or not, if you walk 10 kilometres a week, you'll be nearly 40 per cent less likely to die from all causes and 34 per cent less likely to die from heart disease, the leading cause of death in people with diabetes. The reason? Walking makes your cells more receptive to insulin, which leads to better control of blood sugar. It also raises levels of "good" HDL cholesterol. See "Walking," page 140, for great ways to motivate yourself to walk.
